We are now distributing these bug fixes in version 5.984. Syncdocs will update itself in the next few days. The update can be downloaded now from the Syncdocs download page.

Here's a summary what's fixed:
1. Fix for uploads and updates of files that are locked because they are in use by other applications. These can now be read and hashed.
2. Fix for very long pathnames where the directory name was between 244 and 259 characters, Syncdocs would crash.
3. Better error handling for XP and Windows 2003 Servers that do not have updates installed since 2011.

Note that after updating, you might need to update your firewall to give the new Syncdocs the same permissions as the old Syncdocs after updating, as some firewalls detect a changed updated application as a new program, and prevent it from accessing the Internet.
